What is CVE-2020-23361?

A vulnerability exists in phpList version 3.5.3 that allows unauthorized users to bypass the login mechanism due to an issue with how password hashes are compared. The use of the loose comparison operator (==) instead of the strict comparison operator (===) enables type juggling, particularly impacting hashes that start with '0e' followed by numerical characters, leading to potential unauthorized access.
